Hey guys,
Going through a batch of stuff from a friend of a friend's estate, I came across a Roland JC-120 Jazz Chorus. Always wanted one, so I figured i'd check it out. Anyway, it seems like no matter what the amp settings, both channels, the volume is always on TEN and the volume knobs don't make one bit a difference! Before I get it on the bench taking away valuable space (it's HUGE AND HEAVY) from other projects, any ideas of possible causes? Things to check first? If I get it on the bench, I want to get it taken care of as soon as possible!

edit: Adding a schematic from an '84 - Mine's an '86 (I THINK), but it can't be TOO different!
